| Lab 2.4.2 Switch config. browser - Overview Estimated time: 30 min. Objectives: Use the Management Console menus to view and configure switch IP address settings Check workstation network settings to verify compatibility with switch and router settings Test cabling and IP connectivity from workstation to switch using the Ping and Telnet commands Use a workstation with browser software to connect to the switch and check port status Background: This lab will provide an opportunity to configure a switch for IP and HTTP (Hypertext Transfer Protocol) access. By assigning an IP address to the switch you will be able to ping it and Telnet to it. You will also be able to use your workstation browser (Netscape or Internet Explorer) to connect to the switch and check switch settings and port statistics. The browser will provide a graphical interface showing a frontal view of the switch and allow you to select any port to check out its statistics and characteristics. Many newer switches have HTTP web server software built in to support browser-based switch management. With Cisco switch clustering technology, you can manage up to 16 switches with one IP address. It is very important to assign a password to the switch if you are going to assign an IP address. Tools / Preparation: Prior to starting the lab, the teacher or lab assistant should have a switch available with the default VLAN settings. A workstation with HyperTerminal should be available to console into the switch and an Ethernet connection to Telnet and browser into the switch. Since there may be only one switch available, the instructor should demonstrate this lab at a minimum and students should work in larger teams to get hands on. While one team is doing switch labs the others could be doing web-based research on switches at the Cisco web site URLs listed below. Before beginning this lab you may want to read the Networking Academy Second Year Companion Guide, Chapter 2 –LAN Switching. You should also review semester 3 On-line Lesson 2. The following is a list of equipment required. Windows PC w/ HyperTerminal installed (configured for console connection to switch) Cisco Switch (19xx or 28xx model) Console Cable (roll-over) CAT 5 Ethernet Cable from the workstation to a switch Ethernet port Web Site Resources: LAN Switching basics General information on all Cisco products - (Scroll down to chapter 15 - Switches) 1900 / 2820 series Ethernet switches 2900 series Fast Ethernet switches 3500 series Gigabit Ethernet switches Cisco switch clustering technology Notes: Step 1- Connect the workstation to the switch console port and turn the switch on. Depending on the switch you will need either a rollover RJ-45 cable with a DB9 adapter (on the PC end) or a DB9 to DB9 null modem (modem eliminator) cable. Wait a few minutes for the switch to boot up and it will display a menu of options known as the “Management Console”. 1. What is the model number for the switch? 2. What is the Ethernet Address (Layer 2 MAC address) of the switch? Step 2- Use the Management Console to configure IP access to the switch. The IP address of the switch can be used to Ping or Telnet to the switch and browse into it. It is not required to assign an IP address to a switch but it is recommended for switch management. When managing a switch, the “Management domain” is always VLAN 1. All ports are assigned to VLAN 1 by default. 3. Select [N] Network Management and then [I] IP Configuration from the menus. Assign an IP address and subnet mask to the switch. Be sure to use an IP address and subnet mask that are compatible with the network or subnet the switch is currently on. If the switch is connected to Router Lab-A, Interface E1 (205.7.5.1) as shown in the standard lab setup diagram, then assign a compatible IP address and subnet mask to the switch. IP Address: Subnet Mask: 4. Select [V] Virtual LAN from the menu and verify that all ports are assigned to VLAN 1. List the ports that are currently assigned to default VLAN 1: Step 3- Use the Management Console to configure HTTP access. 5. Select the [N] Network Management menu and verify that the switch will accept HTTP requests. What option is used to configure the switch to be an HTTP server? (Note: This option may not be available on all switches) Step 4 - Configure the workstation for Ethernet access to the switch. Configure the workstation with TCP/IP network settings to be compatible with the switch IP address and the router interface (E1) address. Be sure to set the workstation IP address, subnet mask and default gateway (nearside router interface). 6. Write down the workstation IP address information here: IP Address: Subnet Mask: Default Gateway: Step 5 – Ping the IP address of the switch. Connect the workstation Ethernet cable (straight-through) to port 1 on the switch and use the ping command from the workstation DOS prompt to test connectivity and IP configuration between the workstation and switch. C:\WINDOWS> ping 205.7.5.4 7. Was the ping command successful? Step 6 – Telnet to the switch IP address. Telnet to the switch from the workstation DOS prompt to test upper layer connectivity and IP configuration between the workstation and switch. You should see the same menu as when you are connected via the console. C:\WINDOWS> telnet 205.7.5.4 8. Was the telnet successful? Step 7 – Use your browser to access the switch. Start your browser software (Netscape or Internet Explorer). Type in the IP address you just assigned to the switch in the browser address area where you would normally type in the URL of a web site. The Switch Management Graphical User Interface (GUI) should be displayed by the HTTP server in the switch. Remember you can always use the forward and back buttons with the browser. The browser GUI is somewhat limited in what you can configure. 9. Did the Switch Manager browser interface come up? Step 8 – Make some configuration changes to the switch using the browser interface. 10. Enter a name for the switch: 11. Enter a password for the switch and confirm it. 12. What color will the port be if the link is faulty or the port is disabled? 13. Select the port where your workstation is connected (port 1) and click on it with the mouse. S croll down the port table until you get to port 0/1. What is the current actual duplex mode? Change the mode from Half Duplex to Full Duplex. (The NIC in your workstation may not support full duplex operation). 14. Check the port statistics for frames received and transmitted by clicking on the “Stats” button. Enter the number of packets below: Good Frames Received: Packets Transmitted:
